Christmas In The Stars is a Star Wars Christmas album

Recorded in 1980, Christmas In The Stars: Star Wars Christmas Album features the original voices of R2-D2 and C-3PO. Many of the album's songs were written by Maury Yeston, a Yale University music professor and composer. I managed to find some of the songs on YouTube: here (sung by 18 yr old Jon Bon Jovi!), here and here.
